Neamhain is the Goddess of Light, the sister of Morrighan and Macha, and the last of the three Badhbh Catha Goddesses. Even though she was forgotten during the Human-Fomorian wars, she makes her debut in Generation 10.

Neamhain's intentions are to restore Tir Na Nog and purify it with light, using any means necessary to achieve that goal.
